Korg Sigma

“Korg Sigma Mono synthesizer in good cosmetic condition. As is visible in the pictures, the wood sides have chips / marks and there spots on the front of the synth with paint chipped off. To note, the wood panels have a little play when moving the synth but my understanding is that’s how it is by design. This Sigma was just serviced at Rosen Sound in LA, sounds amazing with aftertouch working fully, and will ship in a custom flight case. Thanks!” Click here to visit listing on eBay

” For sale is my Korg Sigma KP-30 Synthesizer keyboard. It is almost fully functional, however, the right green tab switch on the synthesizer section is not outputting any sound. Everything else is working normally as far as I can tell. This is a Japanese model, and I’m including a 120v to 100v adapter as part of the sale. Also included is the flight case.”

most of these are in a terrible stae the wood and metal but this one lookg just gorgeous

it even has both original joysticks which are almost always missing or replaced

its in fully wokring order with slight crackle when turning the volume knob thats about it

it was one of the first synths with aftertouch for pitchbend and vibrato

its a synthesizer / preset two engine synth

the synthesizer section reminds a bit of the ms-20 series with dual filter

the preset section has still lots of parameters to adjusts on top
